## 添加路由
|
||
|
|
|
||
|
|
> 引发问题场景：
|
||
|
|
>
|
||
|
|
> - 一主机多网卡情况下
|
||
|
|
> - 缺失路由导致无法通讯或主机默认路由网段错误
|
||
|
|
|
||
|
|
| 主机网关 | 是否为 Kubernetes 使用网络 |
|
||
|
|
| :-----------: | :------------------------: |
|
||
|
|
| 192.168.1.100 | 是 |
|
||
|
|
| 192.168.2.100 | 否 |
|
||
|
|
|
||
|
|
1. 查看默认路由
|
||
|
|
|
||
|
|
```bash
|
||
|
|
ip route show default
|
||
|
|
```
|
||
|
|
|
||
|
|
> 查看路由基础命令
|
||
|
|

|
||
|
|
> - 查看路由
|
||
|
|
>
|
||
|
|
> ```bash
|
||
|
|
> route -n
|
||
|
|
> ```
|
||
|
|

|
||
|
|
> - 查看路由
|
||
|
|
>
|
||
|
|
> ```bash
|
||
|
|
> ip route
|
||
|
|
> ```
|
||
|
|
|
||
|
|
2. 添加默认路由
|
||
|
|
|
||
|
|
```bash
|
||
|
|
route add default gw 192.168.1.100 dev eth0
|
||
|
|
```
|
||
|
|
|
||
|
|
> 或使用 `ip route` 命令
|
||
|
|
>
|
||
|
|
> ```
|
||
|
|
> ip route add default via 192.168.1.100 dev eth0
|
||
|
|
> ```
|
||
|
|
|
||
|
|
3. 刷新路由缓存
|
||
|
|
|
||
|
|
```bash
|
||
|
|
ip route flush cache
|
||
|
|
```
|
||
|
|
|
||
|
|
4. 添加路由后，需要重启 Kubernetes 网络插件
|
||
|
|
|

|
|
## 遇到问题
|
||
|
|
|
||
|
|
> 如果已存在默认路由呢？
|
||
|
|
|
||
|
|
**删除默认路由**
|
||
|
|
|
||
|
|
```bash
|
||
|
|
route del default gw 192.168.2.100 dev eth0
|
||
|
|
```
|
||
|
|
|
||
|
|
或
|
||
|
|
|
||
|
|
```bash
|
||
|
|
ip route del default via 192.168.2.100 dev eth0
|
||
|
|
```
